If the crazy they grabbed in MD is the guy, I will be eating two days worth of crow. I really don't want this to be a home grown nut.
Brian Wilson on Fox just reported:
The police responded to a report of shots fired at the house. When they arrived, they saw a man leaving the house. The police arrested the man. The police went inside to look for victims but they did not find any victims. They did see lots of guns. Now they are getting a search warrant so they can go back and search the house properly. The police had talked to this man sometime in the recent past.
Although they did not say this on Fox, I think the police are very interested because their geographic profile says the shooter lives in that general area and this man has guns.
